Abstract:
We prove that there are exactly $149$ genus two curves $C$ defined over $\mathbb {Q}$ such that there exists a nonconstant morphism $\pi :X_1(N)\rightarrow C$ defined over $\mathbb {Q}$ and the jacobian of $C$ is $\mathbb {Q}$-isogenous to the abelian variety $A_f$ attached by Shimura to a newform $f\in S_2(\Gamma _1(N))$. We determine the corresponding newforms and present equations for all these curves.References
